Operation in a 10 kWth Chemical-Looping Combustor for Solid Fuel - Testing with a Mexican Petroleum Coke

• Solid fuel chemical-looping combustion was investigated in a 10 kWth combustor using petroleum coke as fuel and ilmenite as oxygen carrier. Testing involved operational parameters variations, such as particle circulation, fluidizing velocities, fuel load and fuel reactor temperature.Key parameters indicating the performance include CO2 capture, solid fuel and gas conversions from the fuel reactor. The CO2 capture averaged at 75%, the solid fuel conversion at 65-70% while incomplete gas conversion led to an oxygen demand averaging at 29-30%, due to presence of CH4, CO, H2 and H2S. Effect of fuel reactor temperature on the solid fuel conversion was verified.
